I

As herein exemplified,the invention is embodied 1n a mach ne where n thestereotype plate is slid or placed freely within the cylinder with itsstraightedgesresting on horizontallyv disposed ftracks or guidei ways,the cylinder thereuponbeing calledinto rotation byifhan'ds operatedmeans.

the 'cylinder begins to rotate, the mechanism looks or clamps theg platefirmly within the "cylinder and .so holds the plate 'as it passes nearthe center of FigLl- (and looking at.

the trimming and shaving'fdevices, The trimmingand shavlng. arecompleted on a "single revolution ofthe cylinder, and as the cyl ndercomes to 'rest on the Icompletion'of such revolution, the; stereotypeplate isu-nlocked or unclamped;preferablyby alltOf maticallyoperatingdevices, preparatory, to its removal from the machine, -either hand orby mechanical means. -It1will be understood, however, that in certain ofits" features or aspects the invention isapplica- ,ble 'to other formsof machines than the "embodiment. V

one briefly described above and hereinafter described in detail as thepresent preferred 4 Referring now indetail to the exemplifiestion of theaccompanyingdrawings, the irvention is shown applied to and constitutinga partof a stereotype plate trimming niachine, in which machine the castplate is re from the casting machine ceived with the tail or riserattaclied'thereto,

plate sliding upon its straight edges-upon tracks or guides locatedlongitudinally and i very nearly centrally within the cylinder. its theplate runs or slides in upon the guides, it fits loosely within theccylinder, the convex or printing surface on the ex- ".erior of the platebeing thus, and thereby out of contact with the inner surface or thecylindrical body of the machine. 1 r

the machine, passing out in the sainejdirection but at the opposite endfrom i which'it. came in. The plate is usually conveyed out Preparatoryto starting the machine on th trimming operation, the stereotype platea" is raised from the guides and is clamped i firmly and closely againstthe inner surface of the cylinder; After the plate so clamped, thecylinder makes a rotation, and during such rotation the two ends of theplate are carried past rotating saws, located atj-either end of thecylindrical body of the inachin'e,and the head of the plate is there-.by'trimmed and the tail thereof is severed from the plate, and that endof the plate also properly trimmed. Atfthe same time, the concave backof the plate is carried past one or more fiXed shaving knives, whichshave the surface of' the concave ribs on the back of the plate in awall known manner.

The plate is then'unclamped, and'as so finished or perfected drops toand rests on its straight-edges upon the tracks or guideways withintliemachine body. It is then slid along the tracks or guideways out ofof the trimming'machine proper, as justdescribed, by automaticallyoperating lllGCllanisin, but such mechanism is not shown or described inthepresent case, as any form'. of withdrawing means may be employed sofar as the present invention is concerned.

p The present invention as applied to such a machine, relates primarilyto novel means operating automatically to clamp the stereotype plate, asalready. described, prepai'a tory to trimmingor fiI11Sl1111g,tlI1Clsecondari- 1y to means cooperating therewith for effecting otherfunctions, such as automatic means forunlocking the'plate after it hasbeen trimmed or finished and means for 'eflectin b and controlling therotation of the cylinder, 7 together with the other niechanisms hereinferred'to. r a I 7 Referring now to thedetails of construction of theembodiment illustrated in the ac 'companying drawings, a platecarryingcyl- 1nder 1 is arranged preferably horizontally,

and is supported in a pair of annularfranies or bearings 'Qa'ndfi,within which frames the cylinder is rotatable. I The annularbeain frames2 and 3 ai'e'mounted upon a suite h t. l L

able machine base 4, inc traekways or centrally and longitudinally ofthe interior wall "or the cylinder l, very nearly asemi' circumferenceapart, so that as the plate 00 is slid into the machine, its straightedges will rest u on and slide alon the 'uides o ly positioned in frontof the machine to aid in this operation;

The embodied form of means for trinimingthe head and'cutting oifthe tailof the plate w comprises rotarysaws 10 and 11, T

at the opposite ends of the cylindrical body 1 of the machine.- The saws10 and 11 are guides Sand? ai'eai'ranged within and near ator, asuit-abletable or support beingusuat 9 in our ,copend fixed upon a shaft12 mounted in bearings 13 and i l carried upon the machine base ThesawslO and 11 iiiay beprotected by casings 10 and 11 respectivelysecuredto the bearings 1st and 13.: The shaft 12 is driven in anysuitablemanner, as by gear 15 driven byfiany suitabledevices, not shown I Theshaving of the'concave inner ribs of the stereotype plates s effected byone or more shaving knives or blades 16, indicated conventionally in thedrawing; 7

A machine of the general type so far described is shown and described inPatent No; 1,126,741 to Wm. Evensen dated Feb.

2, 1915. In t e present the stereotype plate holdii'ig'and clampingmeans, is designed and constructed to 013 preferred embodiment of crateinconjunctionwith the machine start!v r 'ing and machine stoppingdevicesor mechanisms, that is the devices for starting and stopp ng therotation of the cylinder 1 to effect the finishing of the plate andthereafter to leave. it in position to be withdrawn or discharged uponthe completion of the llnlslllllg operation. In the embodied andexemplified form V of 7 means for rotating the cyl nder 1, a gear a 11mmI 7 ring 26 encircles the cylinder 1, and has 'tion f the cylinder 1from the gear as will be later described.

, The gear ring is loose onthe cylinder and i p is driven bysuitablemeansnot shown The unclamp the plate afterthe completion ofplate clampingidevice comprises a cam 615' gear ring 26 is comiectableto and discon- 'n'ectable from the cylinder 1,to eifectthej rotation ofthe cylindertogether-with effecting certain otherfunctions, as willhereinafter appear.

Referring now to the embodied form of plate clampingmeans, mechanism ispro,-

vi-ded adapted to engage with-one of the straight edges of the plate, tolift it'ofl' [the guide 6 or 7 andto press the 'platefirmly and solidly,and yet Without toofmucl1 -pres-' sure, against the interior ofthecylinder 1.

In theembodied form, this means is p osir' tively acting, but this isnon essentialsofar asconce' rns nany features of the present n: I

ated clamping blocks 4:5 are. provided mounted on the cylinderll andlocated breaks or interruptions in the guideway or track 6 or7,;jand areslidable to and fro to. clamp and to uncla'mp the plate. The

clamping block asshown has its upper surface even with or .justbelow-the top of the track 7 while'the plate is being fed in, and ispressedupwardly by mechanism set. in motion by the operator instartingthe machine. In its upward movement it lifts the, plate, fromtrack 7 (asshown in Fig. 2) and presses the plate against the interiorof cylinder1, preparatory to the'finishingoperationj. Block 45 is moved downwardlyautomatically by the machine to. free or the finishing operation,permitting its f straight edgeto rest upon the track orgiiide 'way7,preparatory to the feeding outlor discharge of the finished plate.

As embod'ed', the clamping block is fixed to "afslid-e 46, and fixed to.the slide 46 is afblock 47,,with which block the actuating means for theclamping device cooperates. Suitable supporting and guiding meansfor Ithe members 45,4;5- an'cl t'i arerprovided, and
